Subject: Re: Local variables & blocks


The proposed new rule is that a variable introduced in a block (other than
the block parameters) is not local to the block but the enclosing scope.
So in effect you can do then:

def summer(*args)
  args.each { |arg| sum += arg.to_i }
  sum
end

Today you have to write

def summer(*args)
  sum = 0
  args.each { |arg| sum += arg.to_i }
  sum
end
